Once you cast this spell, you hold its energy to empower another spell you will cast later. Once before the spell ends, you can either grant yourself advantage on one spell attack roll or impose disadvantage on one saving throw made by a target against a spell you cast.
In addition, if the spell which you enhanced with one of the effects described above deals damage, you can reroll any damage die that rolls a 1. You must use the second roll for each die, even if the damage is lower.
At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, when rerolling damage dice for a spell you enhanced, you can reroll any damage die that rolls a 1 or a 2.
